House washing in Chattanooga typically costs $250–$400 for most homes, depending on size, siding type, and how much mildew/algae buildup is present. For many homes, soft washing is the preferred method because it cleans thoroughly without risking damage to siding, paint, caulk, or landscaping.
If your home looks dingy, has green growth on shaded sides, or shows dark streaking under gutters, it’s likely time for a wash.
What’s the Difference Between Soft Washing and Pressure Washing?
Soft washing:
-
- Low pressure
- Uses cleaning solutions to kill organic growth
- Ideal for vinyl siding, painted surfaces, stucco, and delicate areas
Pressure washing:
-
- Higher pressure
- Best for hard surfaces like concrete and some masonry
- Can damage siding if used incorrectly
For most exterior house washes, soft washing delivers a deeper clean because it treats the cause (mildew/algae), not just the surface.

You may need it sooner if:
- Your home is shaded or near dense trees
- You get heavy pollen buildup
- You see recurring algae on one side of the home
Risks of Using Too Much Pressure on a Home
